near the generator.

WARNING

Do not operate the generator inside a room, cave, tunnel, or other
insufficiently ventilated area.
Always operate it in a well-ventilated area, otherwise the engine may
become overheated, and the poisonous carbon monoxide gas, an
odorless, colorless, poison gas, contained in the exhaust gas will
endanger human lives.
Operate generator only outdoors and far from open windows, doors,
ventilation intakes and other openings.
Keep the generator at least 1 meter (3 feet) away , including overhead,
from any structure or building use.

1m

1m

ENGLISH

WARNING

Do not enclose the generator nor cover it with a box.
The generator has a built-in forced air cooling system, and may become overheated if it is enclosed.
If generator has been covered to protect it from the weather during non use, be sure to remove it and
keep it well away from the area during generator use.

WARNING

Operate the generator on a level surface.
It is not necessary to prepare a special foundation for the generator.
However, the generator will vibrate on an irregular surface, so choose a level place without surface
irregularities.
If the generator is tilted or moved during operation, fuel may spill and / or the generator may tip over,
causing a hazardous situation.
Proper lubrication cannot be expected if the generator is operated on a steep incline or slope. In such
a case, piston seizure may occur even if the oil is above the upper level.

WARNING

Pay attention to the wiring or extension cords from the generator to the connected device.
If the wire is under the generator or in contact with a vibrating part, it may break and
possibly cause a fire, generator burnout, or electric shock hazard.
Replace damaged or worn cords immediately.

−1−

WARNING

Do not operate in rain, in wet or damp conditions, or with wet hands.
The operator may suffer severe electric shock if the generator is wet due to rain or snow.

WARNING

with water.

WARNING

Be extremely careful that all necessary electrical grounding procedures are followed during each and
every use. Failure to do so can be fatal.

WARNING

Do not contact the generator to a commercial power line. Connection to a commercial
power line may short circuit the generator and ruin it or cause electric shock hazard.
Use the transfer switch for connecting to domestic circuit.

WARNING

No smoking while handling the battery. The battery emits flammable hydrogen gas,
which can explode if exposed to electric arcing or open flame.
Keep the area well-ventilated and keep open flames/sparks away when handling the battery.

WARNING

Engine becomes extremely hot during and for some time after operation.
Keep combustible materials well away from generator area.
Be very careful not to touch any parts of the hot engine especially the muffler area
or serious burns may result.

WARNING

Keep children and all bystanders at a safe distance from work areas.

WARNING

It is absolutely essential that you know the safe and proper use of the power tool or appliance that
you intend to use. All operators must read, understand and follow the tool/appliance owners manual.
Tool and appliance applications and limitations must be understood. Follow all directions given on
labels and warnings. Keep all instruction manuals and literature in a safe place for future reference.

WARNING

Use only "LISTED" extension cords.
When a tool or appliance is used outdoors, use only extension cords marked "For Outdoor Use".
Extension cords, when not in use should be stored in a dry and well ventilated area.

WARNING

Always switch off generator's AC circuit breaker and disconnect tools or appliances when not in use,

6. WATTAGE INFORMATION

Some appliances need a "surge" of energy when starting.
This means that the amount of electrical power needed to start the appliance may exceed
the amount needed to maintain its use.
Electrical appliances and tools normally come with a label indicating voltage, cycles / Hz,
amperage (amps) and electrical power needed to run the appliance or tool.
Check with your nearest dealer or service center with questions regarding power surge of
certain appliances or power tools.

■

Electrical loads such as incandescent lamps and hot plates require the same wattage
to start as is needed to maintain use.

■

Loads such as fluorescent lamps require 1.2 to 2 times the indicated wattage during
start-up.

■

Loads for mercury lamps require 2 to 3 times the indicated wattage during start-up.

■

Electrical motors require a large starting current. Power requirements depend on the
type of motor and its use. Once enough "surge" is attained to start the motor,
the appliance will require only 50% to 30% of the wattage to continue running.

■

Most electrical tools require 1.2 to 3 times their wattage for running under load during
use. For example, a 5,000 watt generator can power a 1800 to 4000 watt electrical
tool.

■

Loads such as submersible pumps and air compressors require a very large force to
start. They need 3 to 5 times the normal running wattage in order to start.
For example, a 5,000 watt generator would only be able to drive a 1,000 to 1,700 watt
pump.

NOTE :

The following wattage chart is general guide only. Refer to your specific appliance for
correct wattage.

To determine the total wattage required to run a particular electrical appliance or tool,
multiply the voltage figure of the appliance/tool by the amperage (amps) figure of same.
The voltage and amperage (amps) information can be found on a name plate which is
normally attached to electrical appliances and tools.

VOLTAGE DROP IN ELECTRIC EXTENSION CORDS

When a long electric extension cord is used to connect an appliance or tool to the
generator, a certain amount of voltage drop or loss occurs in the extension cord
which reduces the effective voltage available for the appliance or tool.
The chart below has been prepared to illustrate the approximate voltage loss when
an extension cord of 300 feet (approx. 100 meters) is used to connect an
appliance or tool to the generator.

9. "HOW-TO" MAINTENANCE

ENGINE OIL CHANGE

■

Change engine oil every 100 hours.
(For new engine, change oil after 20
hours.)

(a) Drain oil by removing the drain plug

and the oil filler cap while the engine
is warm.

(b) Reinstall the drain plug and fill the engine with oil until it reaches the upper level

on the oil filler cap.

■

Use fresh and high quality lubricating oil to the specified level as directed on page 7.

If contaminated or deteriorated oil is used or the quantity of the engine oil is not
sufficient, the engine damage will result and its life will be greatly shortened.

SERVICING THE AIR CLEANER

Maintaining an air cleaner in proper condition is very important.
Dirt induced through improperly installed, improperly serviced or inadequate
elements damages and wears out engines. Keep the element always clean.

(a) Remove the bolt of air cleaner cover. (RGX7100, 7800)

Remove the air cleaner cover and cleaner element.

(b) Urethane form : Wash urethane form element in kerosene or diesel fuel. Then

saturate the element in a mixture of 3 parts kerosene or diesel fuel and 1 part
engine oil.
Squeeze the element to remove the mixture and install it in the air cleaner.

Oil drain plug

ENGLISH

NOTE :

Instead of washing oil (kerosene), it is possible to wash the urethane foam element

in a solution of mild detergent and warm water.

Then rinse the element thoroughly in clean water.

Allow the element to dry thoroughly. Soak the element in clean engine oil and
squeeze out excess oil.

CHECKING CARBON BRUSH

Brush Maintenance Essentials (Effective Length)

The brush is the area which touches the slip ring, and its surface must be kept
smooth.

If it is not smooth then carbon and other substances will adhere between the brush
and slip ring.

This must be buffed with sandpaper or the like because it is hazardous.

The usable length of the brush is 5~11mm, so if the brush is 5mm long or less
replace it with a new one.

This is done because if the length of the
brush gets any shorter, its contact
pressure with the slip ring will decrease,
resulting in a drop in generator efficiency
and the output voltage.

ENGLISH

Check the brush every 500 hours to
confirm its length.

In addition, check the brush length if the
generator malfunctions, such as when it is
not generating power or its voltage is low.
